Okay so here is the scenario.
A PO was created.
It's got a simple workflow, underwent it so it was approved, then confirmed.
Afterwards an item arrival journal was created, but delivery was over the ordered quantity, so when the user tried to generate a product receipt, there was an overdelivery error.
Now, the purchasing user change requested the PO, and edited the lines with overdelivered qty. It was then submitted to the workflow and was completed.
Now, the thing is when they try to confirm the PO again, this error pops up
Do you guys have any idea how to fix this?
